3. AAC block can be used for wall, Floor and roof decks of
buildings. AAC Blocks are used much like regular concrete blocks.

4. AAC Blocks are most recommended to be used on high-rise
buildings.

5. AAC blocks are planned with dimension accuracy and compressive
strength. It can be used in many load bearing application, whether
it is a large, Small or tall job. AAC blocks walls installed using
this bed mortar function as a monolithic structure is provides
better strength as compared to the concrete block /clay brick
building.

6. AAC Blocks do better than concrete and bricks. AAC blocks are
the only durable, thermal and fire rated material all in one
product.

HowAAC (Autoclaved Aerated Concrete) production line working ?

First of all, dosing of the stored raw materials

Feed raw materials into the pouring mixer and evenly mixing

Poured the slurry into the mould

Static stop and pre-curing under a certain temperature, the slurry
become a big block

The big block had a certain of hardness,then be hanged for 90
degree by turning hoister

Open the mould and de-moulding,The big block will sit on the one
side plate

and 8. Horizontal cutting the big block

9. Vertical cutting the big block

10. Hanging semi-product to hardening car

11. Entering autoclave

12. hardening

13. leaving autoclave

14. Hanging and stacking of end products

15. loading and packing

Feature of AAC:

1. Thermal Insulation

It has highest thermal rating in the industry….R30! Thus provides
well insulated interiors, keeping out warm air in summer and cold
air in winter. AAC reduces Air conditioning cost by 30%.

Earthquake forces on structure are proportional to the weight of
the building, hence AAC shows excellent resistant to earthquake
forces. Regions of high seismic activity like Japan exclusively use
AAC. It has been proven to withstand wind loads of category 5
tropical storms.

4. Floor Space Area

Use of thinner blocks (6" instead of 9" exterior walls) because of
its excellent water barrier & insulation properties leads to an
increase in floor space area between 3-5%.

5. Cost saving

Being lightweight AAC drastically reduces the dead weight of
building, resulting into reduction in steel (up to 27%) and cement
(up to 20%) structural cost saving.Being 8 times the size of a clay
brick, AAC wall construction involves 1/3 the joints, thus an
overall mortar saving up to 66%.

Best in class fire rating of 4 hours. The melting point of AAC is
over 1600 ºc, more than twice the typical temperature in a building
fire of 650 ºc.

AAC land and workshop require:

300000m3 to 400000m3,workshop is 8000m2,the land is 25000m2.

Changzhou Mingjie building Material Equipment Manufacturing
Co.,LTd, located in zhonglou development zone in Changzhou, had
been established for more than 30 years and also exported the AAC
block / panel production line over ten years.

1. The International standardization professional plant

The company covers an area of about 48,000 square meters, a total
of five international standardization professional workshops,
respectively, for the storage of raw materials, cutting of sheet
metal, finish machining of parts, assembly of equipment, and
classification and maintenance of finished products, easy to do
quality detection in accordance with the international rules and
regulations by the quality department.

2. Advanced production and inspection equipments

The company has strong technical force, has invested more than 100
million to purchase and improve the production and testing
equipment. So far, the company has more than 30 sets of precision
grade CNC lathes and CNC milling machines with the machining
accuracy of ±1 to 1.5μm. In order to meet the demand of large and
medium-sized workpieces’ manufacturing, the company purchased
three sets of large gantry CNC milling machines with accuracy up to
±2μm. At the same time, in order to meet the needs of special
processing as well as accuracy inspection, the company is also
equipped with five sets of CNC plasma arc and flame double-purposed
cutting machine, three sets of CNC laser cutting machines, more
than ten sets of CNC presses, CNC plate shearing machines, CNC
bending machines, and more than ten sets of high-precision CNC
multi-coordinate measuring instruments.

3. Complete quality control system

To meet the consumers’ needs, as well as the needs for product
quality control and brand building, the company executives develop
the clear quality policy and objectives, and set up a laboratory
dedicated to quality testing. The company invests a total amount of
500million for infrastructure and equipment procurement of the
quality testing laboratory , which building area is over 300 square
meters, also equipped with more than 10 sets of imported testing
equipments..
